The Lowdown

Alright, this is Rusty. Let’s have a look at what’s on the cards for Jaconé over the next couple of weeks.

The good news is there’s surf pretty much the whole way through, starting from Saturday the 8th of August, and it kicks off with a decent pulse. There’s a bit of a wait for the real magic though.

We start off on Saturday afternoon with a clean little 3ft swell from the SSW, period at 12 seconds, and the water’s sitting at a balmy 73°, which is about 2° warmer than normal for this time of year – nice. The energy is weak though, only reading 242, so it’s small but workable if you’re keen for a cruise.

The standout window opens on Sunday morning the 9th. We’ve got a solid 7ft SSW groundswell, period a fat 14 seconds, and the wind is a light NNW breeze keeping it cross-off. The energy jumps right up to 1534 – that’s proper power. This is excellent, clean surf for experienced surfers. The crowd factor is “sometimes”, so you might have a few out, but it’ll be worth it.

Monday the 10th and Tuesday the 11th keep the size up around 7ft to 8ft from the S, with periods holding at 12-13 seconds. The wind on Tuesday morning and afternoon turns cross-off from the ESE and E, keeping it clean. This is more excellent, powerful surf for those who know what they’re doing.

Wednesday the 12th through Friday the 14th holds that 6ft to 7ft range, but conditions get a bit mixed. Wednesday morning is a highlight with offshore ENE wind at 9 mph, keeping it clean, but the afternoon gets a bit chunky with a 16 mph cross-off. Thursday morning the 13th is another winner with NE offshore at 6 mph and a clean 6ft S swell.

We roll into the weekend of the 15th and 16th, and the quality drops off. The swell is still there, 6ft to 7ft, but onshore SW winds mess it up. Not the time to paddle out.

Now, the second week brings a shift. From Monday the 17th, the swell drops to 5ft to 6ft and the period shortens right down to 8 seconds from the east. This is weaker, short-period stuff. The standout here is Tuesday morning the 18th – glassy conditions with NE wind at 3 mph, and a 5ft E swell. That’s a gorgeous morning for a longboard or a fish.

Later in the week, we see another solid pulse. Thursday morning the 20th has a clean 7ft S swell, period 11 seconds, with light offshore ENE wind. That’s another one for the experienced crew.

The final days, from Saturday the 22nd into Sunday the 23rd, are smaller – 4ft to 5ft – but the conditions are clean. Sunday afternoon the 23rd is a real treat: glassy, with a 4ft S swell at 13 seconds. A beautiful way to close out the outlook.

So, for the best of the best: lock in Sunday morning the 9th of August for that powerful, clean SSW groundswell, and Thursday morning the 20th of August for another clean, solid S swell. Don’t sleep on Tuesday morning the 18th if you want a glassy, easy-going session.

Stay safe, and don’t be a hero in the onshore slop.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
